On and off red spotting

Caitlin

Hi guys 👋🏽 currently about 6 weeks 2 days pregnant Witt my first pregnancy. Went to the ER a few days ago for red spotting (no clots or cramps) followed by a nose bleed, doctor told me my cervix was still closed and that they can see a sac no baby yet. Yesterday I had more red spotting that stopped after about 5 minutes again no clotting or cramps just wondering if this is normal? Starting to think that my cervix is probably sensitive
